【摘要】 利用广州地震台测震数字记录资料与模拟记录资料,对数字记录的震相到时、震级、地震波形清晰度、连续率与模拟记录进行对比分析,结果显示,数字记录与模拟记录的震相到时、震级差别不大,而地震波形清晰度、连续率则数字记录优于模拟记录。更多还原

【Abstract】 Using the digital data and analog data from the digital record of Guangzhou Station, we contrast the seismic phase arriving in time, magnitude, waveform definition, continuous ratio of digital record with that of analog record. The result shows that the differences between the seismic phase arriving in time and magnitude of the digital record and that of analog record are small, but waveform definition and continuous ratio of the digital record excel that of analog record.更多还原
